I don't even know too much linux stuff yet (more than some I guess, but less than you) and that install guide was more than enough. And it's worth it._________________Gentoo and Doom III. 'Nuff Said.

If you don't want to print out the install guide from the website. Move over to another screen (Alt-F2) and press enter. Then type, without quotes, "less /install.txt". You can follow along while installing. That is what I did. To go back to the install screen press Alt-F1.
